Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an induction heating cooker, and particularly to its cooling structure.

Structure of conventional example and its problems As shown in Figs. 1 and 2, the conventional induction heating cooker has the following features:
An intake port 3 is opened on the bottom surface 2 of the main body near the cooling fan motor unit 1 built into the main body, and the fan motor unit 1 is supported by being connected to the bottom surface 2 of the main body around the intake port 3. Body 4 is formed. In order to avoid contact with the heating coil 6 and the heating coil fixing base 6, the support body 4 is placed in a line A that connects the respective centers of the heating coil 6 and the fan motor unit 1. 9. ．．
It is provided in a direction perpendicular to 11°. When the fan motor unit 1 rotates clockwise, the cooling air is sent out with force as shown by the arrow in the figure (the area indicated by the extra 1 m is in the shadow of the support 7 of the support 4 of the fan motor unit 1). The cooling wind is so strong that I feel like I'm running out of water.

However, since this part is originally the shortest part of the path connecting the air intake port 3 and the exhaust air port 8, it is the optimal place to place the cooling fan 10 of the power transistor 9 (which activates the heating coil 5). In order to compensate for the fact that the cooling air is not strong enough to spread, it was necessary to increase the size of the cooling fins 10 for heat dissipation of the power transistor 9. Also, the heating coil behind the cooling fins 10 Although the diagonal line 86, which is off the fixed base 6, is an appropriate place to place parts with large height dimensions, it is difficult to place parts with low temperature because the cooling is strong and the line A does not shift. .

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to eliminate the area where cooling air is difficult to reach, which is caused by the support of the fan motor unit.

Structure of the Invention In order to achieve the above object, the induction heating cooker of the present invention includes a cooling fan motor unit built into the main body,
It is equipped with an air intake port on the bottom surface of the main body near the fan motor, and a fan motor dry knit support that connects to the bottom surface of the main body around the air intake port. This configuration has the effect of eliminating areas where the pillars of the fan motor unit support act as a barrier and the air from the fan motor unit is difficult to reach because of its strong air flow.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 3 and FIG. 4 (A), an air intake port 13 is opened on the bottom surface 12 of the main body near the cooling fan motor unit 11 built into the corner inside the main body. is fixed by a support 16 supported by a strut 14.15 connected to the strut 1
4 is provided along the side wall surface 17 of the main body.

The operation of the above configuration will be explained below.Since the support 14 of the support 16 of the fan motor unit 11 is provided along the side wall surface 17 of the main body, cooling air is sent out when the fan motor unit 11 rotates clockwise. The flow is as shown by the arrows in the figure, and as shown by arrow B, cooling air flows strongly from the intake port 13 to the exhaust port 18 along the main body side wall surface 17. Therefore, the cooling air strongly hits the heat radiation fins 20 of the power transistors 19 placed on the path of arrow B, and cooling is performed well, so that one heat radiation fin 20 can be made smaller. In addition, since the cooling air also hits the components 21 placed behind the radiation fins 20, the heating coil 22 and the heating coil fixing base 23 are removed from the heating coil 22 and the heating coil fixing base 23, making it a convenient place to place the heat generating part. becomes.

In this way, according to this embodiment, the pillars of the two fan motor unit supports serve as a barrier, allowing cooling air to spread to areas where it was difficult for cooling air to reach, and making it particularly convenient for placing heat-generating components. It has the effect of being able to.

Effects of the Invention As described above, according to the present invention, the support section of the fan motor unit support acts as a barrier to the cooling air sent out by the fan, making it particularly convenient for arranging heat-generating components in areas where it is difficult for the cooling air to spread. It can be the location of.
